EMBALMERS DRAINAGE-TUBE.

Specification of Letters Patent.

Patented Feb. s, 1921.

Application led August 2, 1920. Serial No. 400,785.

To all whom t may] concer/n.:

Be it known that l, Parnu filoni-Tano, a citizen ofi the United States,residing at Minneapolis, in the count)7 oit Hennepin and State ofMinnesota, have invented certain new and useful lmproveineiits inlnibaliners Drainages'lubes; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make'and use thesaine.

This invention relates to an improved drainage tube for use inembalining, and one object ot the invention is to provide a device ofthe character described including a suction tube and a vent tube havingconnection With ahead Vwhich will serve to prevent the tubes from beingchoked and further serve as supporting means holding the tubes in theirproper operativo relation.

Another object of the invention' is to provide improved means torclosing the vent tube When necessary, the closure being mounted upon thesuction tube and movable thereon into and out ot position to close thevent tube` Another object oi* the invention is to so construct thisdevice that the head or nozzle as it ma)7 be termed may be taken apartto permit oit thorough cleaning.

Another object ot the invention is to so construct this device that itwill be simple in construction and easy to take apart or put together.

This invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a view showing the improved device in side elevation.

Fig. 2 is an enlarged vertical sectional view through the head or nozzleand portions of the vent and suction tubes.

Fig. 3 is a transverse sectional vievv taken along the line 3 3 of Fig.1.

Fig. 4 is a transverse sectional view through the head or nozzle takenalong the line 4--4 of Fig. 1.

Fig. 5 is a transverse sectional vievv taken above the head along theline 5-5 of Fig. 1.

This improved draining device or tube is provided With a cylindricalhead or nozzle 1 Which is provided with a closed lower end 2 havingopenings 3 formed therein so that liquid may pass through these openingsand into the interior of the nozzle. The walls of the nozzle adjacentthe open upper end Which is internally threaded, are provided withlarger openings d which also permit of the passage of liquid into theinterior of the nozzle. A plug 5 is screwed into the internally threadedupper end portion of the nozzle and provided with an outstanding iange 6at its upper end for engaging the end of the nozzle as shown in Fig. 2and thus limiting' movement of the plug into the nozzle and furtherpermitting the plug to be easily put in place or removed. This plug isprovided with openings T and 8 to receive the vent tube 9 and suctiontube 10. the vent tube terminating at the inner end of the plug and thesuction 'tube extending down into the nozzle to a point adjacent theclosed lower end thereof. These tubes 9 and 10 entend in parallelrelation and are connected by the collar 411 so that the tubes 'will beheld in the proper spaced relation and prevented from movingtransversely. From an inspection of Figs. 3 and 5, it will be seen thatin addition to the openings 7 and S to receive the tubes 9 and 10, theplug 5 is provided with openings 12 so that liquid may pass throughthese openings into the interior oi the nozzle. rlhe tube 9 terminatesshort ot the outer end of the tube 10 and in order to close this venttube when desired, there has been provided va plate 13 which is slidablymounted upon the suction tube 10 and, provided with a plug 14 forfitting into and closing the open upper end of the vent tube 9. It willthus be seen that `when it is desired to prevent air from 'entering thenozzle 1 through the tube 9, it is only necessary to slide the plate 13down upon the tube 10 until its plug 14C enters and closes the upper endof the tube 9.

W hen this device is in use, the tube of a suction pump oit anyconventional construction will be connected with the enlarged upper endoi: the suction tube 10 and the device vvill be inserted in an openingformed in the body to be drained. When the suction pump is in operation,the liquid or semiliquid materials to be drawn out Will pass into thenozzle or housing 1 through the openings Q., i and 12 and will be drawnout of the nozzle through the suction tube 10. lf it is desired to havethe vent tube 9 open, the plate 14C will be moved to the dotted lineposition shown in Fig. 1 or if itis desired to have this tube closed toprevent passageV ci' air throu h the same the closure late v P Will bemoved to the operative position shown. A iter the draining has beencompleted, the device Will be removed and can be easily and quicklycleaned by removing the hollow nozzle or housing l from the plug 5. Thedevice can then be thoroughly cleaned and reassembled. lt will thus beseen that there has been provided a drainage device which Will be veryeflicient in operation and which may be easily and quickly cleaned whennecessary.

I claim:

l. A drainage device comprising a tubular housing open at its upper endand having its bottom and side Walls provided With Y inlet openings, aplug screwed into the open upper end of the housing, a suction tubeextending through the plug into the housing to a point adjacent thebottom thereof, a vent tube extending through the plug parallel to thesuction tube and terminating short of the upper end thereof, and a plateslidably mounted upon the suction tube above the vent tube and having aplug :tor itting into and closing the open upper end oi' the vent tube.

9. A drainage device comprising a suction 'tube and a vent tube, plughaving the vent tube and suction tube extending through openings formedtherein, a perforated housing carried by the plug and forming a nozzlehaving the suction tube extending therein7 and a closure for the upperend of the Vvent tube carried by the suction tube.

3. A drainage device comprising a suction tube and a vent tube7 a plughaving the vent tube and suction tube extending through openings formedtherein and serving as means for carrying the tube in operativerelation, and a perforated nozzle carried by the plug with the suctiontube extending beyond the plug into the nozzle.

4. A drainage device comprising a nozzle having inlet openings and openat its upper end, a closure for the open upper end of the nozzle, asuction tube carried by the plug and extending through the same into theinterior of the nozzle, a vent tube extending through an opening formedin the closure and having its outer end portion connected with thesuction tube, and means for closing the open upper end of the vent tubeadjustably carried by the suction tube.

5. A drainage device comprising a pericrated nozzle, a closure for oneend oi the nozzle, a suction tube extending through the closure into thenozzle, and a vent tube eX- tending through the closure forcommunieating With the interior of the nozzle.

ln testimony whereof I have hereunto set my hand in the presence of twosubscribing Witnesses.
